FRACTURE-BOX.

To all whom it may concern Be it known that 1, Nuts Swanson, a citizenof the United States, residing at Muscatine. in the county ofliiluscatinc and State of Iowa. have invented certain new and usefulImprovements in Fracture-Boxes of which the following is aspecification, reference being had to the accompanying drawings.

This invention relates to new and useful improvements in fracture boxes,the object of the invention being; to provide an appa ratus of the abovecharacter which is especially adapted for use in the treatment offractures in the lower portion of the le Another object of the inventionis the provision of a device of the above character wherein the legsupporting member is adjustable to permit of the leg being raised orlowered, as desired.

A further object of the invention is to provide a fracture box of theabove character whereby the same may be readily adjusted longitudinallyto adapt the same to legs of various lengths.

A still further object of the invention is the provision of a fracturebox of the above character which will possess advantages in points ofefliciency and durability, is inexpensive of manufacture and at the sametime is simple in construction and operation.

WVith the above and other objects in view, the invention consists in thenovel features of construction and the combination and arrangement ofparts to be hereinafter more fully described, pointed out in the claimsand shown in the accompanying drawings, in which Figure 1 is a sideelevation illustrating the manner of use; F ig. 2 is a top plan view;Fig. 3 is a transverse sectional view taken on the line 33 of Fig. 2;Fig. 41 is an end elevation, parts thereof being removed; Fig. 5 is afront end elevation; and Fig. 6 is a top plan View, the leg supportingmember being removed.

Referring more particularly to the drawings, 1 indicates the base memberwhich is preferably hollow in cross section and slidably mounted uponthe bottom thereof is an adjustable member 2 and arranged within thebase and secured to the central partition 3 thereof is a rigid member4:, to the outer end of which is hingedly connected the supportingmember 5, the upper end of said supporting member being hingedlyconnected to a second supporting member 6 which Specification of LettersPatent.

is arranged beneath the box 7 and disposed between the two guide members8. Mounted upon the supporting member 5 and adapted to more therewith isa bridge plate 9, the purpose of which will be hereiimfler more fullyset forth.

liingedly connected to the outer end of the adjustable member 2 is thethigh box 10, the upper end of which is adapted to normally rest uponthe bridge plate 9 and may be moved to various adjusted positions andretained in such position by means of the pivoted arms 11 which arepivotally connected, as shown at 12, and having the end portions thereofconnected to the base and the box 1.0. Mounted upon the bridge plate 9are the side boards 13, which are adapted to be arranged between theextended ends of the thigh box 10. These side plates 13 are connected toand are movable with the bridge plate 9. The ex tended ends 14 of thefracture box 7 are curved downwardly and provided with the elongatedslots 15 in which the headed pins 16 are movable, said pins beingcarried by the side plates 13 so as to retain a connection between thefracture box and the side plates.

The bridge plate 9 and the fracture box 7 are pivotally connected bymeans of the links 17, one end of which is pivotally connected to thebridge plate and the other end pivotally connected to the supportingmember (3. ivlounted upon the base 1 are the spaced bearings 18 in whichare mounted the ends of the shaft 19 and mounted upon one end of theshaft is a wheel 20 whereby said shaft Rio end with an outwardlyprojecting arm 21, the outer end of which is hingedly connected, asshown at 20 to the supporting member 6 so that upon the rotation of theshaft 19, the fracture box 7 will be raised or low cred as desired.

Mounted upon the end of the shaft opposite the Wheel 20 a collar 23,which is provided with a plurality of openings 24; adapted to receivethe downwardly projecting h e 25 which is formed upon the outer end ofthe pivoted pawl 26 so that when the fracture box has been raised orlowered to the desired position, the lug 25 will engage within one ofthe openings :24 and retain the shaft 19 against rotation.

At one end of the fracture box 7, an ad justable end plate 27 isprovided which is hingedly connected to the bottom of the fracture box 7and is adapted to provide a suitable foot rest to prevent furtheroutward movement of the leg when arranged within the fracture box. Theend plate 27 is re tained in various adjusted positions by means of theside bars 28, one end of each of said side bars being pivotallyconnected to the upper end of the plate 27 at each side thereof, whilethe other end of each of the side bars is provided with a plurality ofteeth 29 adapted for engagement with a pin 30 upon each side of thefracture box to retain the end plate in various adjusted p0 sitions. Theserrated ends of the bars 28 are arranged behind the guide rod 31 so asto prevent any lateral movement of the bars 7 during the operation.

Secured to the outer face of the plate 27 is an angular bracket 32 atthe lower end of which is mounted a pulley 33 over which a cord 34 isadapted to pass, one end of said cord extending up and around the footand is to be suitably padded, as shown at 35, so that the same will notcause any friction with the foot, the other end of said cord extendingdownwardly over the pulley and havin suitable weights 36 secured theretoso that the padded portion 35 will be securely retained in positionaround the foot so as to securely hold the foot in its proper position.From this it will be seen that after the leg has been placed inposition, the padded portion 35 of the cord 34 is adapted to be arrangedover the instep of the foot and the weight 36 placed thereon so as tosecurely hold the foot in position.

In Fig. 1, I have illustrated in dotted lines, a leg in its operativeposition within the fracture box, the lower portion of the leg beingarranged within the box 7 while the upper portion thereof is e Tangedwithin the box 10. It will be readily apparent that in placing the legwithin the fracture box, the knee should be arranged directly betweenthe two boxes 7 and 10, so that when the shaft 19 is rotated to raisethe box 7, there will be no opposition in the bending of the knee.

It will be readily apparent that my device, as illustrated anddescribed, is extremely simple in construction, effective in operation,and can be manufactured and placed upon the market at a very small cost.

It will be apparent that during the adjustmentof the fracture box 7, theupper end of the box 10 which is engaged with the bridge plate 9 will beraised or lowered according to the adjustment of the fracture box.

lVhile I have shown and described the preferred form of my invention, itwill be obvious that various changes in the details of construction andin the proportions may be resorted to for successfully carrying myinvention into practice without sacrificing any of the novel features ofconstruction or departing from the scope of the appended claims.
